CC   -!- FUNCTION: Part of the multicomponent 3-phenylpropionate dioxygenase,
CC       that converts 3-phenylpropionic acid (PP) and cinnamic acid (CI) into
CC       3-phenylpropionate-dihydrodiol (PP-dihydrodiol) and cinnamic acid-
CC       dihydrodiol (CI-dihydrodiol), respectively. This protein seems to be a
CC       2Fe-2S ferredoxin. {ECO:0000255|HAMAP-Rule:MF_01650}.
CC   -!- COFACTOR:
CC       Name=[2Fe-2S] cluster; Xref=ChEBI:CHEBI:190135;
CC         Evidence={ECO:0000255|HAMAP-Rule:MF_01650};
CC       Note=Binds 1 [2Fe-2S] cluster per subunit. {ECO:0000255|HAMAP-
CC       Rule:MF_01650};
CC   -!- PATHWAY: Aromatic compound metabolism; 3-phenylpropanoate degradation.
CC       {ECO:0000255|HAMAP-Rule:MF_01650}.
CC   -!- SUBUNIT: This dioxygenase system consists of four proteins: the two
CC       subunits of the hydroxylase component (HcaE and HcaF), a ferredoxin
CC       (HcaC) and a ferredoxin reductase (HcaD). {ECO:0000255|HAMAP-
CC       Rule:MF_01650}.
CC   -!- SIMILARITY: Belongs to the bacterial ring-hydroxylating dioxygenase
CC       ferredoxin component family. {ECO:0000255|HAMAP-Rule:MF_01650}.
